All morphometric variables are
derived from digital elevation models (DEMs). Example*. A DEM of Mount Ararat was extracted from the SRTM1 DEM. Elevation
approximation was carried out by the universal spectral
analytical method using
300 expansion coefficients of the original function of elevation by the
Chebyshev polynomials. The
model includes 779,401 points
(the matrix 1081 x 721); the grid spacing is 1". The vertical
exaggeration of the 3D model is 2x. The data processing and modeling were carried out using the software Matlab R2008b.
